Amines are produced when a hydrogen atom in ammonia has been replaced by an alkyl or aryl group. Examples of amines are biogenic amines, amino acids and aniline.
Cyclic amines are organic compounds that contain a nitrogen atom within a ring structure. They exhibit unique properties due to their cyclic nature, such as increased stability and different reactivity compared to acyclic amines. Cyclic amines are commonly used in various applications in organic chemistry, including as catalysts, ligands in coordination chemistry, and building blocks for the synthesis of pharmaceuticals and natural products. Their diverse properties make them valuable tools in the field of organic chemistry.
It means in chemistry, the group -NH2, present in amino acids, amides, and amines.

German's won the battle of amines
Aliphatic amines are stronger bases than aromatic amines because the lone pair on the nitrogen atom in aliphatic amines is more available for donation due to the absence of resonance effects that stabilize the lone pair in aromatic amines. This makes aliphatic amines more likely to accept protons and act as bases.
The key difference between amine and amide functional groups in organic chemistry is the presence of a nitrogen atom bonded to hydrogen in amines, while amides have a nitrogen atom bonded to a carbonyl group. Amines are basic and have a lone pair of electrons on the nitrogen atom, while amides are less basic and have a resonance structure due to the carbonyl group.
Ammonia belongs to the class of compounds known as amines. Amines are organic compounds that contain nitrogen as the key element, with ammonia being the simplest example.
Secondary amines produce N-alkyl-substituted formamides, while tertiary amines form N-alkyl-substituted chloroformamides when heated with chloroform.
Chemistry is known from prehistoric times.
Not necessarily. Amines contain nitrogen, but many do not contain oxygen.
The strongest base known to chemistry is lithium hydroxide (LiOH).
